Yep Clink, that's the real solution!
To be fair I think the majority of frames in the Evo genre were intended to be run with a single front ring and the use of 2 * and 3* chainsets was an option rather than what they wre designed around.
CRC's evergreen sale hastop swing front mechs from £7.49 for an old LX, £12.99 for Deore and £14.99 for XT buy all three and see what fits best and send the other 2 back

Looks nicer without decals
Here's the mod you need to do....:

And yes it hurts!
I believe the front mech modification is the same that Cy recommends / has to do for the Solaris.
1x10 is really the best way to go 🙂
Tomaso, I've got an old LX 9sp mech on which works, so I'm guesing most Shimano bottom swing mechs will fit...
The fact that Brant's on here sorting out problems and giving advice is appreciated. It's one of the reasons I go back to On One for frames (well that and the way they ride).
Thanks.

Bottom swing ... as in conventional? Happy to have a go hacking at mine if need be. I have an FDM661, an X9 and an old XT available ... all conventional bottom swing. Also have a Dremel I've never used 🙂
Edit: thanks Stoner ... even I can do that mod.

I don't think I'm buying a Fireline (not what I want at the mo) but the above makes it much more likely I'll buy an On One in the future.
Though personally I'd 1x10 it
There you go. Really chaps, do you need a front mech? Take your triple crankset, put a nice SS chainring in the middle (hard wearing, deep teeth, no shifting ramps etc etc), and drop the mech, shifters and cabling. And free up the bit of your brain that does front shifting and devote it to enjoying your ride.
And thats the front mech mod required for the newer Turner Sultan 29ers, so sounds like quite a common issue, not peculiar to On One?
To be fair, it's the fault of Shimano for being lazy with their front mech production 😆
Edit: Actually, thinking about it, I would say that the number of bikes frames/designs with this issue highlights that Shimano need to be listening to users / manufacturers and responding to demand. There is clearly a design / compatibility issue with their current cost saving design and the market has changed and they need to be listening and adapting.
This talk of 1x10 is all very well, but is very dependent on where you live and ride. I live in Highland and and my bread and butter ride is a 1500 foot climb up Cnoc Fyrish from my house. I would definitely be off pushing much of the ascent on a 29er with only a 32t up front and even 36 on the rear. That's not what I want from my main HT.
XX1 may be the panacea, but I can't justify the cost.
great thread 🙂
Metalheart and Stoner - thanks those pics are useful. My old non-dual-pull LX mech fits, so yes, perhaps Shimano need to revisit their design and go back to top and bottom-pull specific mechs, given the rise in popularity of 29ers? Would prob put the price of mechs up though unfortunately...
So are we saying that you have to hack a mech up and run a 2.1 tyre and not go out in the mud....
Please don't respond with 'go 1 x 10' as it simply doesn't work for the vast majority of people for the bulk of their riding.
Actual clarity on the front mech issue is what i'm looking for, Brant i am happy to buy you 3 pints to find out if this frame is right for me. Plus I could go riding for a couple of days... ummm... barman!
Please don't respond with 'go 1 x 10' as it simply doesn't work for the vast majority of people for the bulk of their riding.
Dunno about that mate. 1x10 with a 32T front sprocket really is pretty steep climbing gearing on an MTB?
So are we saying that you have to hack a mech up and run a 2.1 tyre and not go out in the mud....
Not sure where the 2.1 tyre only and not going out in the mud comes from??? No the consensus seems to be if you want a short chainstay 29er then be prepared to compromise, otherwise go out and buy a long chainstay Ti29er such as a Salsa Mariachi ti or a Lynskey for twice the price 🙄
EDIT and in anycase wont a top swing/low clamp work better here as it moves the clamp below the point where the tyre is closest to the seat tube
Andy, no the top swing mech has the pivot mechanisms and cable clamp sitting behind the seat tube and above the level of the clamp, right where the tyre clearance is at its minimum. Conventional top clamp/bottom swing mechs have all of this more to the side. This is certainly the case on all the Shimano mech's I have to hand.
Ah fair enough 😀
People have been cutting up down-swing FDs like that for a long time, seems a sensible mod.
they already do - the newer direct-mount FDs with the modified cage shape. But direct mount frame fittings look can ugly / be unnecessary for 1x set ups, I like the trimmed down-swing mech option. Jones bikes have been built up that way for ages, there's not a lot of mud room on mine with a std top-swing mech and that has a curved ST and stays over 435mm.There is clearly a design / compatibility issue with their current cost saving design and the market has changed and they need to be listening and adapting.
News from Neil:-
[i]"X9 2x10 fits a treat, plenty of clearance, no mod needed! Top clamp, bottom swing.
X0 and XX are the same so will be fine, not sure about X7 as they have a bulkier clamp design as opposed to the nice neat steel band."
[/i]
Picture coming shortly.

Any way of testing X7 ... there's a groupset I'd buy in the classifieds if I knew it would work.
attaboy two-wheeled dialing diabolists, this thread is coming alive and up from 6 faltering pages to 8 in just 18 hours, but more importantly, full of useful/decent info that will have us riding our fireline evo's this weekend or, depending on delivery, pre-xmas... Keep the relevant gen coming!
some built-up pics and riders' thoughts would be great ...(don't just say "It's good", say why).
There's actually a bit you can cut off those X9/XO (and X7) mechs that would give even more clearance too. Neil says no point. I would though.
Pic... Hang on.
Typical, dont think i will be riding mine tomorrow, i seem to have picked something up that has turned me into a turd factory and rendering me unable to sit down 😯
[i] turned me into a turd factory and rendering me unable to sit down[/i]
tuck your trousers into your socks would be my advice.
Containment is key under these circumstances.
Where's the pics bigdugsbaws ... of the bike not the turds. Missus has conformed mine has arrived at home ... I'm in Dingwall about to hit the drink tho.
Nearly finished but the way im feeling it will be tomorrow before pics.
Douglas, if you can work a keyboard, you can work the ****in camera. 😯
Aye but i have to be within a certain radius of the bog. Besides its dark outside.
My colleagues in the states are going to post pics of their build here today -
I don't know if this helps anyone but here are a couple of pics of how far I got last night. It shows the closeness of the rear tyre, but that is a 2.3.
My dual pull XT front mech defo won't fit though 😥
Seems a bit smaller than my 456ti, shorter wheelbase and top tube. Not sure how that will affect its ride, as a 26er I'd think I've bought a size too small? Time will tell.
Wow, that does look tight on a 2.3
Looks great though
It looks well finished; not sure an Ardent 2.4 or Hans Dampf 2.35 will fit with much room though?
Blimey, an 8-page thread that's both on-topic and not a flame-a-thon?
To whom do I complain?
Looks like it'd work a treat with a 650B back wheel. 😆
It looks well finished; not sure an Ardent 2.4 or Hans Dampf 2.35 will fit with much room though?
Hans Dampf on a Flow going in in the next couple of days. Given this is the 29er rim/tyre of choice right now I'll let you know.
Just checked mine over and despite me being pished it looks wonderful.
Pics aren't great as it was pishing down but mine is done. Really chuffed with it and its coming in at 26 lbs dead with the build shown with no flimsy parts. (frame was 3.7lbs for 20"). For reference a Hans Damph fits in the back with clearance, rear tyre on mine is a Spesh Purgatory 2.3". A joy to build too, the threads were beautifully clean and cable routing perfect 😀

lovely looking thing that, how short are those chain stays!!!
Ooh that looks stunning. Looking forward to a ride report.....
Congrats - looks the business!
Nice looking bike. It doesn't need logos IMO. Ride report when you get a chance please.
Can anyone help?
Really interested in getting one of these frames but not sure what size to get. I'm 5'9" with a 31" inside leg. Currently ride a medium tallboy and medium swift. Really wanting a 29er version of my old 456ti which was a 16".
Any thoughts on whether I should go for a 16" or 18"?
Chris
That I like.
Edit: ... a lot.
ikimbunza - an inch taller than you and rode a 16" 456. Asked Brant same q and response was 16".
Looks great Doug.
bigdugs-what is that stand over height roughly?
Cheers Pete, I'm such a tart I just bought a black fork though..... 😳
Groundskeeperwilly its 31.5" vertically in line with th bb (dont know where you measure on a sloping tt!)
What you doing with the white forks...? 😉
Thanks for that info, too tall for me I reckon.
That's 31.5in on a 20in frame.
A 16in will be a lot lower. I'll see if I can do some sums.
It's a good job there's no SS version or I'd be spending the Christmas money on one of them.
(Will there be a SS version just out of interest...?)
Very nice, what are the forks? Looks a bit like the chromag rootdown, got my heart set on the dialled pa29, but Ti for this price is very tempting. Don't need those decals.
I've decided against it, to me the geometry looks a bit odd and I'm not too keen on the mega short rear stays, just ordered a Lynskey 29 Pro VF instead?
Geo odd? You mean more trail orientated rather than xc? And the chainstays are short-ish, not mega short.
Almost there with my 18" build. Will post pics tomorrow. It looks a lot of fun, not really like any 29er I've seen. I think it'll be well suited to the riding around here.
Predictably, the main concern is the clearance between the rear tyre and seat tube. Reckon it's 3mm with a Hans Dampf ... little room for a front mech and zero chance of running a cable to one.
Am starting out 1x10, buy that won't meet my needs. Be interesting to see what works for others. My other option just now is a Mud X, but they don't last too well on rock and scree.
Took mine to Dalbeattie for a shakedown today as there are a good mix of trail types to test it(About the only places in Scotland without horizontal rain according to Metoffice!)
As with other slack angled 29ers I have ridden, it takes a while to get used to low speed technical stuff as the steering feels a little floppy initially. You also need to ride the fork when cornering to get the best out the bike, but when you do the steering is just fapping ace.
Climbing is not a weak point despite the slack head angle and it doesn’t seem to wander on really steep stuff which is great. It won’t win any XC races on the ups but its not slow by any means and its super easy to lift your front wheel over any obstacles in the way thus minimising stalling.
Pointing the Evo downhill, it rides very like a Yelli Screamy*; super confident, begs to be popped of every rock and root and capable of stuff that you think hardtails cant do well. If you like air, so does the Evo and it feels super stable going off drops and over jumps, even for mediocre riders like me!
Initially sitting on the Evo, it felt a little short and the front end was a bit high due to the tallish headtube but a flatter bar and 80mm stem should give the perfect cockpit so its not a concern. Besides fit is very individual so ignore me.
*(formerly owned and much missed)
So - how does it compare to the YS?
The YS is brilliant and I'd love to ride one back to back with the Fireline but the latter is considerably more compliant(in a good way) and cheaper. If you lived in the states and benefitted from low Canfield prices, the YS would win hands down on the best bang for your buck, over here my money would go on the Evo.
Spent another few hours behind the bars today on some familiar GT trails. All I will say is the frame gets better and better the more you ride it, felt perfect fit wise despite no overnight fettling too.
Where are all the other builds ???? 😀
Sorry bigdug. I've finished mine for the most part but need to trim the reverb cable and tinker with the gears a bit. I only rode it briefly but it feels wonderful ... like it could take on anything. Think I'm gonna hurt myself on this 🙂
Bedmaker off here tried it to and loved it. It's such a fun bike ... more agile than I could imagine any 29er being. I'm already thinking this for Morocco in April rather than the 5 Spot.
I'll get pics up soonest. Looks quite different in the 18".
Rorschach, what the front mech, it looks like it will receive a full outer?
I was held up with "headset gate" now progressing with the arrival, today of a smoothie. Being done in tactical visits to the garage (being Xmas eve and all that)
Anyone got a front mech working yet?
Where is the adaptor available in UK?
Ison bring problem solvers stuff in.Not listed on the site but the press fit ebb's weren't till I pestered them to get some 😀
Nice thanks
Yelli Screamy's rule the world
loving the pics guys, if anyone has pics of the 18" built up please do post. also can anyone confirm the seat post diameter? there was some confusion a few pages back.
Lovely looking build
Cracking build Swayndo, thanks for the pics and the info! real shame the seatpost is the wrong size 🙁
this frame may "force" me onto XX1................... LOL... 😯
Nice build Swayndo, now go get it filthy!!!
On ma way squire 🙂
Lecht ... my thoughts exactly ... when its available down the range.
The frame looks fab in all the pics - but that rear tyre clearance still looks very tight, even for mud clearance on 1x9/10/11 😯
